Protože je už po aprílu, můžou strahováci opět zveřejnit program další Virtuální Bastlírny, aniž by připravená témata působila dojmem, že jde o žert. Vězte tedy, že již v úterý 7. dubna od 20:00 proběhne VB, kde se setkají bastlíři, technici, učitelé i nadšenci do techniky a kde i vy se můžete zapojit do družného hovoru, jako by všichni seděli u pomyslného piva. Co mají bastlíři tento měsíc na srdci? Pravděpodobně by nás musel zasáhnout meteorit

VOID (Video Object and Interaction Deletion) je nový open-source VLM model pro editaci videa, který dokáže z videí odstraňovat objekty včetně všech jejich fyzikálních interakcí v rámci scény (pády, kolize, stíny...) pomocí quadmaskingu (čtyřhodnotová maska, která člení pixely scény do čtyř kategorií: objekt určený k odstranění, překrývající se oblasti, objektem ovlivněné oblasti a pozadí scény) a dvoufázového inpaintingu. Za projektem stojí výzkumníci ze společnosti Netflix.
Design (GitHub) je 2D CAD pro GNOME. Instalovat lze i z Flathubu. Běží také ve webovém prohlížeči.
Příspěvek na blogu herního enginu Godot představuje aplikaci Xogot přinášející Godot na iPad a iPhone. Instalovat lze z App Storu. Za Xogotem stojí Miguel de Icaza (GitHub) a společnost Xibbon.
Na čem pracují vývojáři webového prohlížeče Ladybird (GitHub)? Byl publikován přehled vývoje za březen (YouTube).
ESP-IDF (Espressif IoT Development Framework), tj. oficiální vývojový framework pro vývoj aplikací na mikrokontrolérech řady ESP32, byl vydán v nové verzi 6.0. Detaily na portálu pro vývojáře.
DeepMind (Alphabet) představila novou verzi svého multimodálního modelu, Gemma 4. Modely jsou volně k dispozici (Ollama, Hugging Face a další) ve velikostech 5-31 miliard parametrů, s kontextovým oknem 128k až 256k a v dense i MoE variantách. Modely zvládají text, obrázky a u menších verzí i audio. Modely jsou optimalizované pro běh na desktopových GPU i mobilních zařízeních, váhy všech těchto modelů jsou uvolněny pod licencí Apache 2.0. Návod na spuštění je už i na Unsloth.
Cursor (Wikipedie) od společnosti Anysphere byl vydán ve verzi 3. Jedná se o multiplatformní proprietární editor kódů s podporou AI (vibe coding).
Průkopnická firma FingerWorks kolem roku 2000 vyvinula vícedotykové trackpady s gesty a klávesnice jako TouchStream LP. V roce 2005 ji koupil Apple, výrobu těchto produktů ukončil a dotykové technologie využil při vývoji iPhone. Multiplatformní projekt Apple Magic TouchstreamLP nyní implementuje funkcionalitu TouchStream LP na současném Apple Magic Trackpad, resp. jejich dvojici. Diskuze k vydání probíhá na Redditu.
